Import Tips & Compliance
• Verify stainless steel grade (e.g
• 304 or 316) via material certificates to meet HTS classification and avoid reclassification
• Ensure thread pitch and shank dimensions are documented as under 6mm for customs; mismatches lead to audits
• Label packaging clearly as 'machine screws' not 'bolts' to distinguish from larger fasteners
